Hi,
I had a friend from Moscow with very limited English vocabulary, especially for food. He loved Denny's menu because he knew at a glance what he would be served.
I will often compare the picture to the food delivered to the table. I check the plate's composition and look to see if everything promised in the photo is present. This can sometimes come back to bite the restaurant. If the soup noodles pictured have three tempura shrimp, they better have those three shrimp.
My knowledge of Korean food advanced considerably once I found a picture recipe book. Suddenly dishes like bi-bim-bop had context, which no server could ever offer.
I don't mind pictures, dessert cart displays or Japanese-style plastic food presentations if they illuminate my understanding of their food offerings. I will often look at other tables to see what they are enjoying, which often influences my choices. The pictures on this website are useful tools, also. While few menus are loaded with pictures, there are occasions I wished there were more used. I have had a few rude surprises of dishes presented did not match my mind's eye expectations. I eat my errors in judgement, though I am sure a picture might have helped keep my expectations balanced and likely made other choices.
Regards,
